SSL decryption help?

I'm having problems making SSL decryption work.

I'm running wireshark 1.6.2

Compiled (64-bit) with GTK+ 2.24.6, with GLib 2.29.92, with libpcap 1.1.1, with
libz 1.2.3.4, with POSIX capabilities (Linux), without libpcre, with SMI 0.4.8,
with c-ares 1.7.4, with Lua 5.1, without Python, with GnuTLS 2.10.5, with Gcrypt
1.5.0, with MIT Kerberos, with GeoIP, with PortAudio V19-devel (built Jul 27
2011 11:52:20), without AirPcap.
Running on Linux 3.0.0-20-generic, with libpcap version 1.1.1, with libz
1.2.3.4, GnuTLS 2.10.5, Gcrypt 1.5.0.

I have a self signed certificate generated with java keytool. I have extracted and converted the private key with the help of http://rubenlaguna.com/wp/2007/06/29/inspecting-tomcat-https-connection-with-wireshark/index.html/

I have updated wireshark preferences so I have:

ssl.desegment_ssl_records: TRUE
ssl.desegment_ssl_application_data: TRUE
ssl.keys_list: 127.0.0.1,8443,http,/tmp/cert.rsa.key
ssl.debug_file: /tmp/ssl.log

When starting the ssl.log file says:

Private key imported: KeyID 96:8b:93:2b:cb:26:7e:d1:b1:1f:18:d0:22:ba:13:6b:...
ssl_init IPv4 addr '127.0.0.1' (127.0.0.1) port '8443' filename '/tmp/cert.rsa.key' password(only for p12 file) ''
ssl_init private key file /tmp/cert.rsa.key successfully loaded.
association_add TCP port 8443 protocol http handle 0x7fa335b09560

So it looks like the configuration is all OK

I capture a simple HTTP GET request, but it cannot decode the data. It recognises SSL as the protocol and offers "Follow SSL Stream", but all I get is 0 bytes in the resulting dialog.

Below is the rest of the ssl.log:

I’m not sure why it says no decoder available?

What else am I missing???
